ELEVATOR RELAY.

- Application filed December 27, 1924. Serial No. 758,340.

This invention relates to new and useful improvements in elevator floorsignal systems. The object of the invention is to provide a floor signalsystem in which means is pro- Vided forcausing a positive operation andwhereby failure of the signal lamp to light is eliminated.

OllClllt closing switch is V cation and by reference to the A particularobject ofthe invention resides in a novel form of relay for actuating agravity contact, whereby an ehicient and simple signal lamp.

Another feature of the invention is to provide electrically actuatedmeans for resetting the relays and clearing the lamps. A constructiondesigned to carry out the invention will be hereinafter describedtogether with other features of the invention.

The invention will be more readily understood from a reading of thefollowing specifidrawings, in which an example of the invention isshown, and wherein:

Fig. l is a circuit diagram'of the system,

Fig. 2 is a front elevation of the relay panel,

Fig.3,is a partial vertical sectional View on the line 33 of Fig; 2,

Fig. 4 is a cross sectional view on the line 4-4= of Fig. 2, and

Fig. 5 is a detail'of one of the relays showing the dog just after it isreleased from the hook. 1n the drawings the numeral 10 designates apanel upon which a plurality of relays are mounted. This panel may bemounted in a box or case 11, which may be disposed in the pent house,elevator shaft or other convenient place. On each side of the panel aremounted electromagnets12, one foreach floor on each side. In Figs. 2 and8 five magnets on each illustrating five floors, but the number will ofcourse vary with the number of floors in the building. The magnets aresuperposed. In front of each magnet is pivoted an armature hook 13 upona screw 14.

, Each hook has on its side opposite from the magnet a notch 15 at thebottom of Which is formed a stud 16. The hook is pivoted at one cornerso as to normally swing away from the magnet. s

I For each hook is provided a dog 17 mounted on a pivot screw 18 and itsback bevelled at 19 whereby it is reduced to a substantial oint. Thepoint of each dog isundercut to lbrm a finger 20 which engages in thenotch 15 on the stud'16. Each finger normally occuprovided for eachaccompanying pies a horizontal position. Below each dog is a contactpin21. When a magnet is energized it attracts the hook 13 which swingsto the magnet thus carrying the stud 16 from under the finger 20. Thispermits the dog 17 to swing down and rest upon the contact pin 21, as isshown at a in Fig. 2. The lower end of each hook has a bevelled edge 22and when the magnet is de-energized the hook is freed and swings outwardso that its bevelled edge 22 rides up the back 19 and holds the dog onthe pin.

For restoring the parts to their normal position a resetting deviceisprovided for each row of magnets. Each device consists of a verticalrod 23 mounted to slide in angular brackets 24 and 25 mounted on thepanel 10. The rod has a collar 26 alcove the bracket 25 and a collar 27below the bracket. Normall the collar 26 supports the rod on the bracket25; while the collar 27 limits the upward movement of the rod. Aboveeach rod is an electromagnet 28 supported by a bracket 29. Each rod hasa pin 30 under each dog. Thus when one of the magnets 28 is energized itpulls the rod upwardly, whereby each pin 30 engages a dog 1'7 and swingsit up so that the finger 20 rides into the notch 15 and engages over thestud 16. When the rod is freed it drops to its normal position. Thebevelled edges play an important part and the positive action of thehooks and dogs is of great advantage.

In Fig. 1 is shown a circuit diagram showing push buttons A and Blocated at each of the five floors. A plurality of signal lights A and Bareshown and are supposed to be mountedin the elevator, car. The buttonsA are pressed by passengers desiring to go up while the buttons sengersdesiring to go down. A main circuit wire C supplies current to one sideof each button by a branch wire C; also to one side of each lamp bybranch wires C From each up button a wire A leads to one of the magnets12, the top wire leading to the top magnet on the left hand side. Fromeach downbutton B a wire B 'leads to a magnet 12 on the right hand sideof the panel, the top wire leading to the top magnet and so on.

The signal lamps A are for the up si na ls; while the lamps B are forthe down signals. A wire A leads from each lamp A to a contact pin 21 onthe left hand side of the panel 10. A wire B leads from each lamp B toone of the pins 21 on the right hand side dog 17. At, the, bottom "ofthe signal lamps.

are switch buttons, E and F respectively, each having one side connectedwith the circuit wire C by branches C". From the button E a wire E leadsto the left hand magneti s which is connected *ith the wire I) byabranch D A wire F leads from the button F to the righthandmagnet- 28which is connected to wire D by a wire D A'passenger on the second floorwishing to go up pushes the up button A. A signal lamp box'isarranged'ineach elevator car connected in multiple withthe relays of thepanel 10.Current; from the wire C passes through the button A on the second floorover wire C thence by wire A 'to the magnet 12 on'the left hand side ofthe panel 10. The second magnet from the bottom is thus energized, thecircuit'being completed over wires D and D.

When the magnet is energized the hook 13 is swung, whereby the dog 17 isdropped on the in 21. The circuit to the magnet is broken when thebutton is released. When the dog drops onto the pin, the circuit isclosed from wire C over wire C to the up lamp A marked from tne 2,thence over wire A to the pin 21 and thence (log '17 over wires D D" andD.

I The signallight signalbox.

If an operator desires to clear the signal or extinguish the lamp orlamps he pushes the button E which closes the circuit from'wire C overwires C .n to the left hand magnet 28 and thence over wires D andD. Thisenerwill be illuminated at each gizes the magnet'28 which raises thelefthand rod, 23, causing itspins 30'to restore the dogs 17, andhocks 13 totheir normalposition.

lf'a passenger on the fourth floor desires to go down he presses thebuttonB which closes the circuit from wire C over wires G and B to theright hand'magnet 12 atQl and thence over wires D and 'D; This energizesthe magnet w ich' attracts the hook 18 landldrops the dog 17' into thepin 21. The circuit is thus closed fromwire C over wire C through lamp 3at a and thence over wire B r'to the pin 21 and thence through the dog17 and the wires D, D and D.

Various changes in the plurality and location of the parts as well asstructural changes may be made within the scope of" the appended claims.
